I was also banded on 3-4. I think what you said is normal. I have been taking it easy not wanting to over do it. I have been weak and sore but not as bad as I thought it would be. I am really not hungry at all. I have to make myself eat and drink because I know I have to to heal. Hopefully you are getting better each day I know I am. Good Luck it will all be worth it in the end.
